@jeyroll Please note that there's a difference when using --direct. I try to get statistics from the card slot itself, so --direct is more close to metal.

//EDIT: For another test I just putted a sample from /dev/urandom of my desktop onto the sd card. Re-inserted into the phone and tried to read it:
Code:
$ dd if=random.sample of=/dev/null bs=4k
94033+1 records in
94033+1 records out
385162240 bytes (385 MB) copied, 19.3315 s, 19.9 MB/s
So again the 20 MB/s limit that we saw now with two class 10 cards. Has anyone any faster results?

BTW: When testing with such files like the one in my edit make sure (parts of) the file isn't in cache!
